Portal Vein D011169 [A short thick vein formed by union of the superior mesenteric vein and the splenic vein. ]
Porifera D011161 [The phylum of sponges which are sessile, suspension-feeding, multicellular animals that utilize flagellated cells called choanocytes to circulate water. Most are hermaphroditic. They are probably an early evolutionary side branch that gave rise to no other group of animals. Except for about 150 freshwater species, sponges are marine animals. They are a source of ALKALOIDS; STEROLS; and other complex molecules useful in medicine and biological research. ]
Porphobilinogen D011162
Hydroxymethylbilane Synthase D011163 [An enzyme that catalyzes the tetrapolymerization of the monopyrrole PORPHOBILINOGEN into the hydroxymethylbilane preuroporphyrinogen (UROPORPHYRINOGENS) in several discrete steps. It is the third enzyme in the 8-enzyme biosynthetic pathway of HEME. In humans, deficiency in this enzyme encoded by HMBS (or PBGD) gene results in a form of neurological porphyria (PORPHYRIA, ACUTE INTERMITTENT). This enzyme was formerly listed as EC 4.3.1.8 ]
Porphyrias D011164 [A diverse group of metabolic diseases characterized by errors in the biosynthetic pathway of HEME in the LIVER, the BONE MARROW, or both. They are classified by the deficiency of specific enzymes, the tissue site of enzyme defect, or the clinical features that include neurological (acute) or cutaneous (skin lesions). Porphyrias can be hereditary or acquired as a result of toxicity to the hepatic or erythropoietic marrow tissues. ]
Porphyrinogens D011165 [Colorless reduced precursors of porphyrins in which the pyrrole rings are linked by methylene (-CH2-) bridges. ]
Porphyrins D011166 [A group of compounds containing the porphin structure, four pyrrole rings connected by methine bridges in a cyclic configuration to which a variety of side chains are attached. The nature of the side chain is indicated by a prefix, as uroporphyrin, hematoporphyrin, etc. The porphyrins, in combination with iron, form the heme component in biologically significant compounds such as hemoglobin and myoglobin. ]
Portacaval Shunt, Surgical D011167 [Surgical portasystemic shunt between the portal vein and inferior vena cava. ]
Portal System D011168 [A system of vessels in which blood, after passing through one CAPILLARY BED, is conveyed through a second set of capillaries before it returns to the systemic circulation. It pertains especially to the hepatic portal system. ]
alliodorol C588189
E2F5 Transcription Factor D050700 [An E2F transcription factor that represses GENETIC TRANSCRIPTION required for CELL CYCLE entry and DNA synthesis. E2F5 recruits chromatin remodeling factors indirectly to target gene promoters through RETINOBLASTOMA LIKE PROTEIN P130. ]
E2F6 Transcription Factor D050701 [An E2F transcription factor that represses GENETIC TRANSCRIPTION required for CELL CYCLE entry and DNA synthesis. E2F6 recruits chromatin remodeling factors directly to target gene promoters and lacks the transactivation domain responsible for binding to the retinoblastoma family of tumor suppressors. ]
E2F7 Transcription Factor D050702 [An E2F transcription factor that represses GENETIC TRANSCRIPTION required for CELL CYCLE entry and DNA synthesis. E2F7 has two separate DNA-binding domains and binds to DNA independently of a dimerization partner. ]
E2F2 Transcription Factor D050703 [An E2F transcription factor that interacts directly with RETINOBLASTOMA PROTEIN and CYCLIN A. E2F2 activates GENETIC TRANSCRIPTION required for CELL CYCLE entry and DNA synthesis. ]
E2F4 Transcription Factor D050704 [An E2F transcription factor that represses GENETIC TRANSCRIPTION required for CELL CYCLE entry and DNA synthesis. E2F4 recruits chromatin remodeling factors indirectly to target gene PROMOTER REGIONS through RETINOBLASTOMA LIKE PROTEIN P130 and RETINOBLASTOMA LIKE PROTEIN P107. ]
Receptors, Guanylate Cyclase-Coupled D050705 [A class of cellular membrane receptors that either have an intrinsic guanylate cyclase activity or are closely coupled to specific guanylate cyclases within the cell. ]
Stenella D050706 [A genus comprised of spinner, spotted, and striped DOLPHINS, in the family Delphinidae. Schools of Stenella, that may number in the thousands, often associate with schools of TUNA, and are thus vulnerable to accidental harvesting. ]
